Java Program (Vote system)

[eugenechia]

Hello, I'm attempting to do a Java question on Voting system.

The idea goes like this:

There are 10 contestants in a singing competition. The java program will generate random 10 votes for any of the 10 singers. Some votes may appear more than once. (e.g contestant 4 may get 2 votes). This is done with Random number. (Contestant will be numbered from 0 to 9)

Write a thread class VoteThread to run such that it displays the contestant number and the votes.

Here is the desired output:

Here are the votes:
5 1 2 5 5 4 7 2 9 0

Contestant 5 has 1 votes so far
Contestant 0 has 1 votes so far
Contestant 1 has 1 votes so far
Contestant 4 has 1 votes so far
Contestant 2 has 1 votes so far
Contestant 5 has 2 votes so far
Contestant 9 has 1 votes so far
Contestant 7 has 1 votes so far
Contestant 5 has 3 votes so far
Contestant 2 has 2 votes so far

Here are the results:
Contestant 0 has 1 votes
Contestant 1 has 1 votes
Contestant 2 has 2 votes
Contestant 3 has 0 votes
Contestant 4 has 1 votes
Contestant 5 has 3 votes
Contestant 6 has 0 votes
Contestant 7 has 1 votes
Contestant 8 has 0 votes
Contestant 9 has 1 votes

Winner is Contestant 5

Here are my codes so far

Test:

import java.util.*;

public class Test{
	static final int TOTAL = 10;

	public static void main (String[] args){

	int [] votes = new int[TOTAL];
	int [] results = new int[TOTAL];

	Random contestantvote = new Random();

	System.out.println("Here are the votes: ");

		for(int i=0; i<votes.length; i++) {
			votes[i]=contestantvote.nextInt(TOTAL);
			System.out.print(votes[i]+" ");
			}

		System.out.println();

		VoteThread TOTAL = new VoteThread(votes,results);

	    TOTAL.start();

        try
		{
		 	TOTAL.join();
		 }
        catch (InterruptedException e) {}

        System.out.println("Here are the results: ");

      /*  for(int counter=0;counter<votes.length;counter++) {
			System.out.println("Contestant "+counter+" has "+votes[counter]+" votes");
		}*/


	}

}

VoteThread:

public class VoteThread extends Thread{

private int votes [];
private int results [];

public VoteThread(int votes[], int results[]){

this.votes = votes;
this.results = results;
}

	public void run() {

	for(int count=0; count<votes.length;count++)
		{
			results[0] = results[0] + 1;
			System.out.println("Contestant "+ votes[count] +" has "+results[0]+ " votes so far");

		

			try{

					sleep(355);

				}catch (Exception e){}

		}



		}
	}

I'm stuck with producing the output properly for "Contestant x has y votes so far". Cant seem to formulate it.

Can you please point me in the right direction to produce the final results of the voting system as well ?

Thank you

int[] votes= new int[10]; // Create 10 vote-counts
for (int i = 0; i < votes.length; ++i) {
    int idx = (int)(Math.random()*10); // Select the contestant to vote  for
    votes[idx]++; // Increase this contestant's votecount
    System.out.println("Contestant "+i+" has "+votes[i]+" votes so far."); // Print the current votes for contestant i.
}

Something like this should do ;)

Hi there,

thank you for the help. However the requirement is to generate the random numbers in the main thread and do the voting in the VoteThread.

I'm fine with the random numbers, its the voting in the VoteThread that I'm facing issues.

I tried using your method but its not working on my end. mabbe something i din do right ?

Cheers
